Good day to everyone here. Big thanks for all your help as I navigate through all these new information. I have been eyeing a vintage watch for some time now (photos attached below). I’ve done my research with regards to its authenticity but unfortunately it has been limited due to the small number of pictures/info available online for this particular watch. I would greatly appreciate any input from this forum. Thank you in advance. Just a bit of a back story, it is being sold to me for $550 due to a broken self winding. I have been told that it usually retails for around $3800. I plan to have it serviced after purchase.
